Online gambling operators will be forced to tell their customers “chances are you’re about to lose” under a new set of rules in the National Consumer Protection Framework.

Gamble responsibly, the two words that are tacked on to the end of gambling ads and delivered at rapid speed will be replaced from next April with phrases like “chances are, you’re about to lose” and “you win some, you lose more” to take their place.

The new taglines include: “Chances are you’re about to lose”; “Think. Is this a bet you really want to place?” ; “What’s gambling really costing you?” and “What are you prepared to lose today? Set a deposit limit”.

Popular online wagering services Bet365, Sportsbet, Ladbrokes and Pointsbet are among those required to apply the new taglines.

The taglines were informed by research commissioned by the federal Department of Social Services, which included in-depth interviews and focus groups with 224 regular online gamblers, with an additional 5000 surveyed, as well as a survey of more than 1000 members of the general public.
